AI agents for Splitwise
A Monmo AI agent keeps your Splitwise groups up to date the way a tidy flatmate or trip organiser would. It turns receipts from Gmail into expenses, splits them by the shares you agreed, checks balances before anyone settles up and exports the year to Google Sheets. It uses your own Splitwise login and asks before it adds, edits or settles anything.

What agents do in Splitwise
Turn trip receipts into expenses
After a trip it finds the hotel, rail and dinner receipts in Gmail, works out who paid, and lists each one as an expense with amount, date and split. You approve the list and it adds them.
AskAdd the Lisbon trip receipts from my Gmail to the Lisbon group. Hotel split by nights, meals split equally.
Split by shares, not just equally
Not every bill divides evenly. Tell it that Sam stayed three nights and Priya two, or that the car was split by percentage, and it sets unequal shares on each expense and shows the working.
AskSplit the cabin booking by nights stayed: Sam 3, Priya 2, me 4.
Keep the monthly house bills current
On the first of each month it adds rent, energy and broadband to your house group from the bills in your inbox, flags any amount that changed since last month and asks before saving.
AskOn the 1st of every month, add rent, energy and broadband to the Flat 4B group and tell me if any bill went up.
Explain who owes whom before settling up
Before anyone pays, it reads every balance in the group, lists the expenses behind each one and points out entries that look wrong, such as a dinner added twice or a taxi split with someone who was not there.
AskBefore we settle the ski trip, show me how each balance was reached and anything that looks entered twice.
Record a settle-up once money has moved
When a friend pays you back by bank transfer or PayPal, it matches the payment to the balance and prepares the settlement. It is saved only when you allow it; paying someone yourself is a separate card.
AskPriya says she sent me 84 euros on Wise. Check it arrived and record the settle-up.
Draft a friendly reminder
For balances older than a month it drafts a short, polite nudge with the total and the expenses behind it, ready to go out in WhatsApp or by email. Nothing is sent until you approve it.
AskDraft a reminder to everyone who has owed me money in the House group for more than 30 days.
Export the year for your records
In January it exports each group to a spreadsheet with totals by category and by person, so you can see what the flat spent on groceries or what the club trip really cost.
AskExport all my Splitwise groups for 2026 to a spreadsheet with totals by category and by person.
How it connects
- 1You sign in to your own Splitwise account once. The agent sees the groups, friends and expenses your account can see, including entries other members added.
- 2You pick which agents may open Splitwise. A personal assistant agent that already handles your receipts and travel fits best; a sales or engineering agent has no reason to see your shared bills.
- 3Reading groups and balances and drafting expense lists happen without asking. Adding, editing or deleting an expense, recording a settle-up and any payment wait for your approval, because every member of the group sees the change.

Questions people ask
Can an AI agent add expenses to Splitwise for me?
Yes, with your approval. A Monmo agent reads the receipts or bank lines you point it to, works out the payer and the split, and shows the expenses on one card. Once you allow it, it adds them through the Splitwise connection, or in its own browser when the connection does not cover something.
Will the agent pay my friends or settle up on its own?
No. Recording a settlement changes balances that everyone in the group sees, so the agent prepares it and asks first. Paying someone, for example through PayPal or Wise, is a separate step with its own approval card showing the person, the amount and the currency. It never moves money on its own.
Can it split a trip paid in several currencies?
Yes. It records each expense in the currency on the receipt, so the original amount stays visible. If your group prefers one currency, tell it which exchange rate to use, such as the rate on the day or the one on your card statement, and it notes the rate beside each converted expense before you approve.
Is it safe to connect Splitwise to an AI agent?
The agent works through your own Splitwise login and sees only your groups and friends. It reads freely but changes nothing without a card you approve, so friends never find surprise entries. You can watch its screen while it works, keep Splitwise to one agent and disconnect the account whenever you like.
